- BrowserState: inject scroll-tracking JS after page load, report position
via WKScriptMessageHandler (weak ref to avoid retain cycle)
- BrowserView: thin blue progress bar at top of viewport; saves progress
to UserDefaults on dismiss; restores scroll position on revisit
- BookmarkRow: 2px progress bar below tags for partially-read articles
- BookmarksView: loads ReadingProgress.all() on appear, refreshes when
browser sheet dismisses
- ReadingProgress: static helper for UserDefaults-backed [url: Double] store;
removes entry when article is fully read (≥99%)

Tapping a bookmark now opens an in-app WKWebView instead of bouncing to
Safari. Reader mode injects JS to extract article content and rerender
with clean serif typography and dark-mode support. Bottom toolbar has
back/forward, reader toggle, share, and open-in-Safari escape hatch.
